Food chain, in ecology, the sequence of transfers of matter and energy in the form of food from organism to organism. Food chains intertwine locally into a food web because most organisms consume more than one type of animal or plant.
19 de oct. de 2023 · Learn what a food chain is and how it describes who eats whom in the wild. Explore the different trophic levels of producers, consumers, and decomposers, and see examples of food chains in various habitats.
A food chain is a linear network of links in a food web, often starting with an autotroph (such as grass or algae ), also called a producer, and typically ending at an apex predator (such as grizzly bears or killer whales ), detritivore (such as earthworms and woodlice ), or decomposer (such as fungi or bacteria ).
Learn how food chains and food webs represent the flow of energy and matter through ecosystems. Explore the roles of producers, consumers, and decomposers, and the efficiency of energy transfer between trophic levels.
17 de feb. de 2023 · A food chain is a linear sequence of organisms showing how energy or nutrient flows through an ecosystem when one organism consumes another. Learn about the four trophic levels, grazing and detritus food chains, and FAQs on food chains.
15 de jun. de 2023 · A food chain is a group of organisms that are consumed in a linear order, passing nutrients and energy along the way. Each organism in a food chain is at a particular trophic level, which is determined by how many energy transfers distance it from the chain’s primary energy source.
29 de may. de 2024 · A food web is a complex network of interconnecting and overlapping food chains showing feeding relationships within a community. Learn how food webs are structured, powered by the Sun, and include producers, consumers, detritivores, and decomposers.
